osnac103 mutants display green-stay phenotype under dark-induced senescence. A Phenotype of OsNAC103-OE lines and osnac103 mutants under the dark treatment. B Phenotype of detached leaves of OsNAC103-OE lines and osnac103 mutants under the dark treatment. C, D Chlorophyll content analysis of leaves in OsNAC103-OE lines and osnac103 mutants before dark treatment (C) and after dark treatment (D). The leaves with same weight before dark treatment and after dark treatment 7 days were collected to measure Chl content. OE2 and OE7 are two independent OsNAC103-OE lines. CR2 and CR5 are two allelic mutants. Values are shown as means ± SD, n = 3. Asterisks indicate statistically significant differences by Student’s t test (*P < 0.05; **P < 0.01)
